# problem with “one time pad” [closed]

I am a french student and I read the post on the forums (How does one attack a two-time pad (i.e. one time pad with key reuse)?). I need your help if possible. I 'm 11 encrypted messages , all encrypted with the same key. How should I proceed?

In OTP you have $C=K\oplus{M}$. If the key is the same $C1=K\oplus M1$ and $C2=K\oplus M2$, => $C1 \oplus C2$ = $K\oplus M1 \oplus K\oplus M2$ = $M1 \oplus M2$ If you have the same ciphertext, that means that the same message was encrypted. E.g. messages 4,6,7,11 have the same first 6 symbols.
